Sen. Paul responded to criticism that he has faced from neoconservatives about this issue during an interview with Chris Wallace on Fox News Sunday.

“What I’m asking is about drone strikes on Americans, on American soil,” Sen. Paul responded. “The president will not answer that he cannot do this. In fact, he seems to be asserting that he can do this.”

Sen. Paul added, “The CIA is not supposed to assassinate people on American soil and the Department of Defense is not allowed to act on American soil because of the Posse Comitatus Act.”
